Application June 27, 1947, Serial No. 757,420 2 The present invention relates to automatic toilet seat lifters and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

It is anyobject of the invention to provide a means whereby a toilet seat is automatically raised to a vertical position when not in use.

Another object of the invention is the provision of an automatic seat lifter which is easy to install, inexpensive to manufacture and efficient in its operation.

A further object of the invention is the provision of an automatically operated seat lifter wherein means is provided for braking the operation of the same whereby the seat may be lifted with a minimum of noise.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 1 is a side elevational view of an embodiment of the invention,

Figure 2 is a front elevational view of Figure 1,

Figure 3 is an enlarged fragmentary elevational view disclosing certain details of the invention, and

Figure 4 is an enlarged sectional view taken along line 44 of Figure 1.

Generally, the invention provides a device which may be quickly and easily attached to a toiletsseat and to the floor adjacent the toilet 5 bowl assembly and which, when thus attached,

will allow the seat to be moved to a horizontal position when the toilet is to be used and which will remain in such position by means of the weight of the person sitting upon the same. When the person so using the seat arises, springs,

links and a lever will cause the seat to be moved floor adjacent the lower end of the bowl I is aflixed a plate I4 having an integrally formed pair of ears I between which is pivotally mounted the lower end of a lever It by means of a bolt IT. The plate I l has afiixed thereto an upright member I8 which is provided with a. laterally extending bracket I9 provided with a channel '20 in which is adapted to ride a dog 1 Qlairn. (01. 4-251 2 I ll to which is affixed spring 22, the other end of which is attached to the lever I6, as indicated at 23. It will be seen that the rearward portion of the channel extends angularly upwardly, thus causing a retarding action upon the dog 2| when it is forced to change its direction of travel in the channel. To the upper end of the lever I6 there is pivotally connected by means of a bolt 24, a link 25 having a pair of bolts 26 laterally mounted at the upper end thereof, The bolts are adapted to ride in a slot 21 formed in a bracket arm 28 having its upper end pivotally connected, as indicated at 29, to a bracket 30 which is adapted to be fastened to the under side of the seat I2 by means of screws 3!.

An ear 32 is attached to the upright I8 and has pivotally connected thereto, as indicated at 33 the rod 34 of a piston 35 slidably mounted in a dashpot cylinder 36, which cylinder is pivotally connected, as indicated at 31, to the lever I6. A tension spring 38 interconnects an ear 39 carried by the lever I6 and the upright member I8.

In operation, it will be apparent that when the seat I2 is lowered that it will force the bracket arm 28 and consequently the link 25 and the lever I8 forwardly against the action of the spring 38 and that the weight of the person utilizing the seat will hold the seat in a horizontal position. When the person so using the seat arises therefrom, it will be seen that the spring 38 will cause the lever I6 to be moved toward the upright member I8 thereby forcing the seat I2 to reassume a vertical position through the medium of the link 25, the bracket arm 28 and the bracket 30. This upward movement of the seat I2 will be braked through the medium of the dashpot 38 so that the movement of the seat will be a gentle one and it will prevent slamming and consequent marring of the seat I2 and its attendant parts. It will also be seen that as the seat is lowered the compression spring 22 will move with the lever I6 and that the dog 2I will move with the same in the slot 20 and that when the seat is raised through the action of the spring 38, the movement of the spring 22 and dog 2I will be reversed and that the dog will cease its inward movement when it impinges against the arm I8 and that further upward movement of the seat will act to compress the spring 22 to thus absorb any shock which might otherwise occur, thus obviating all noise due to the return of the seat to its normal vertical posi tion.

one end of a compression While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

A seat lifter comprising a floor plate, a stationar vertical arm attached to the plate, a

lever pivotally connected ito the plate a tension spring interconnectingthe arm and" the lever; a bracket attached to the seat, an adjustable link interconnecting the seat bracket and the lever,"

means for braking the action of thEESPIi-I'Ey'fifid; means comprising a dashpot interconnecting the vertical arm and the lever, a bracket-having a horizontal channel therein attachechto the vertical arm, said channel having an angularly and upwardly disposed portion at its rearward end',

a dog slidably mounted in [the channel and a com- -20 pression spring interconnecting the dog and the lever, said angularly disposed portion of; said channel acting as a retarding means to the rearward movement of the dog, in said channel.
